Hello David, I didn't send a grib file because the problem with the cloud rendering is present with any download from ARPEGE, ARPEGE-EU, ICON and ICON-EU. The GFS grib data seem to be ok. Maybe this is related to my computer (Laptop Dell G3, windows10 Home 64bit, Geforce Gtx 1050 Ti) and I didn't try it in another computer yet. Am I the only people who reported this issue? Could I ask if you are using the graphic card to render the images (opengl, directx)?
